Bug: Design Challenge submission fails during active Leaderboards

Issue Description:

When submitting a Design Challenge entry, the submission routine fails on the first attempt whenever the Leaderboard/Voting system is actively tracking scores.

Note: Prior to the last week of the previous CoM, submissions always worked perfectly in a single step.

Observed Timeline:

• Before: Submissions always worked in 1 single step without any issues.
• Previous CoM (Final Week - 6th & 7th Design Challenge): Bug appeared for the first time. Active Leaderboards → Required 2 steps / attempts.
• New CoM (Week 1 - 1st Design Challenge of the new season): Fresh season start / Initial setup phase → Worked smoothly in 1 single step.
• New CoM (Week 2 - 2nd & 3rd Design Challenge): Active Leaderboards running → Failed back to requiring 2 steps / attempts every time.

What Happens During the 2-Step Submissions:

• Step 1 (Failed Upload): Blueprints and completion rewards are credited immediately, but the city layout fails to upload. An error pops up asking to "Check internet connection", and you are returned to the design city.
• Step 2 (Immediate Retry): Submitting a second time right away succeeds instantly.

Testing Done:

I tested this over both my home Wi-Fi and a mobile hotspot (cellular data). The issue occurs identically on both connections. This proves it is not a local network issue, but a server-side bug introduced in a recent update when syncing the city layout upload with the active Leaderboard system.

Request to EA:

Please inspect the server-side submission routine during active Leaderboards to fix these false Iconnection error messages and prevent failed first attempts.
